Penetrants

Zyglo ZL-27A is a general purpose post emulsifiable fluorescent penetrant, used for a wide range of medium to high sensitivity applications.It is typically used on castings, turbine components, welds, forgings, rough and machined surfaces to find cracks, seams, laps, laminations and porosity. It exhibits outstanding penetrating and indication stability characteristics which provides for maximum reliability in locating surface-open flaws and discontinuities It is safe to use on most engineering and aerospace alloys including aluminium, steel, nickel and titanium. This post emulsifiable (post removable) penetrant is formulated to be immiscible with water, this property guards against over-removal from defects by over washing and allows the penetrant to separate readily from water, making effluent clean up easier. ZL-27A is used in conjunction with a hydrophilic remover or lipophilic emulsifier to render them washable with water. The penetrant fluoresce's a bright green-yellow when exposed to ultraviolet radiation (UV-A) peak wavelength of 365 nm. Sensitivity Level 3.
